WRlNGER-PLATE FOR TWISTING AUGERS.

SPECIFICATION forming part of Letters Patent No. 276,043, dated April 17,1883,

Application filed September 29,1882. (ModeL) To all whom it may concern Be it known that I, GEORGE G. HoLLEY, a citizen of the United States, residing at Fisk dale, in the county of Worcester and State of Massachusetts, have invented a new and useful W rin ger for Twisting Angers, Auger-Bits, or other Boring-Tools, of which the following is a specification.

My invention relates tothosewringers whie are located in the head of ahollow shaft adapted to be oscillated or rotated.

My improved wringer is formed with a rectangular slot, flaring or expanding laterally in opposite directions near its ends on its delivery side, to form a twisted slot and to give the desired double twist to the bit or auger plate, which is passed through the rear of the wringer, which, being rapidly rotated or oscillated, causes the plate by its impact against the sides of the slot to follow the direction of the flaring portions and obtain the desired twist. The sides of the wringer are beveled to fit corresponding grooves in the head of the twister.

In order that the invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which Figure 1 is a face view of my improved wringer. Fig. 2 is a rear view thereof. Fig. 3 is an end View. Fig. 4 is a longitudinal section on the line 4 4, looking in the direction of the arrow 4. Fig. 5 is a longitudinal section on the same line, looking in the direction of the arrow 5. Fig. 6 is apartial transverse section of a machine on a smaller scale, showing the Wringer in position and a blank passing therethrough. Fig. 7 is a front view of the twister-head and a transverse section of the plate or blank.

A is my improved wringer, formed with rectangular slot or opening a. The wringer is beveled at each side, cc", to adapt it to slide on a twister-head, B, having grooved face b, and formed on or attached to acentral hollow shaft, b, of sufficient diameter to receive within it the largest size of blank, E, it is desired to twist. This shaft b is mounted in journal-box (J, bolted to standard D, and is rotated or oscillated byanysuitable means. As the twisted blank is forced through the wringer its outer end may be received by suitable dies, F.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent 1. A wringer-plate provided with a rectangular slot, said slot being twisted 0n the delivery side of the wringer-plate, as set forth.

2. The combination of wringer-plate A,having slot a and recesses a a, and the twisterhead B, connected with central hollow shaft, 12, as set forth.
